RFR (L) 8214417: Add space after/before {} in vmTestbase/nsk/jvmti/[A-I] tests

[Alex Menkov]

Ok, guys, you win :)

About the fix:
Looks like only 1-line initializers are fixed, so now we have mixed 
style in some files like:

ClearFieldAccessWatch/clrfldw001/clrfldw001.cpp (lines 52-53 are not 
updated):

NULL },
51     { "nsk/jvmti/ClearFieldAccessWatch/clrfldw001", "fld1", "I", 1, 
NULL },
52     {"nsk/jvmti/ClearFieldAccessWatch/clrfldw001", "fld2",
53         "Lnsk/jvmti/ClearFieldAccessWatch/clrfldw001a;", 0, NULL},
54     { "nsk/jvmti/ClearFieldAccessWatch/clrfldw001a", "fld3", "[I", 0, 
NULL },


The same in ClearFieldModificationWatch/clrfmodw001/clrfmodw001.cpp 
(lines 52-53):
51     { "nsk/jvmti/ClearFieldModificationWatch/clrfmodw001", "fld1", 
"I", 1, NULL },
52     {"nsk/jvmti/ClearFieldModificationWatch/clrfmodw001", "fld2",
53         "Lnsk/jvmti/ClearFieldModificationWatch/clrfmodw001a;", 0, NULL},
54     { "nsk/jvmti/ClearFieldModificationWatch/clrfmodw001a", "fld3", 
"[I", 0, NULL },


GetClassSignature/getclsig006/getclsig006.cpp (44-51)
43     { "getclsig006", "Lnsk/jvmti/GetClassSignature/getclsig006;", 
"NULL" },
44     {"getclsig006b", "Lnsk/jvmti/GetClassSignature/getclsig006b;",
45         "<L:Ljava/lang/String;>Ljava/lang/Object;"},
46     {"getclsig006c", "Lnsk/jvmti/GetClassSignature/getclsig006c;",
47         "<A:Ljava/lang/Object;B:Ljava/lang/Integer;>Ljava/lang/Object;"},

(and others files)
